If you don’t like it, you can turn it off

Cafe. Amsterdam Schiphol train station. I have ordered a tea and am sat at a tall table in the corner to write a few notes and wait for a train. The screen, positioned at head height by the table, is buzzing and I find it an irritating distraction. So I switch it off.

About five seconds pass before I start to worry that someone will arrest me. Or tell me off. I worry I am somehow breaking the rules. I switch it back on and immediately feel like an idiot. I continue writing my notes, warmed by the glow of a sandwich I will not buy.
